VALVE Original Filed Nov. 7, 1929 INVENTOR ATTORNEY! Reisaued Feb. 2, 1932 UNITED STATES PATENT OFFICE HARRY C. LYONS, OF MOUNT VERNON, NEW YQRK VALVE I Original No. 1,818,230, dated August 11, 1931, Serial No. 405,370, filed November 7, 1929. Application for reissue filed September 28,

My invention relates to valves'for dispensing liquids, such as milk and cream, and is of particular utility as applied to so called measuring valves, the main object of the invention being to improve the mechanical construction whereby the same may be rendered not only compact and convenient to the operator, but may be easily and thoroughly cleanseda factor of the greatest importance in the dispensing of the aforesaid liquid foods. I i

'In the drawings I have shown the preferred form of the invention, in which Fig. 1 is a side elevation of my valve as it would appear in use;

Fig. 2 is a front elevation of the same;

Fig. 3 is a side elevation of the-valve proper, the casing and certain associated parts being shown in section; i

Fig. 4 is a section on the line 44 of Fig. 3;

Fig. 5 is a View of the underside of the valve and the housing, the lower cap being removed.-

1 represents a container designed to hold the liquid to be drawn off in measured quantities. The valve measuring mechanism by which the contents of the receptacle 1 are measured and delivered, comprises a casing or valve housing-2, the interior wall of which is slightly tapered. Projecting at an oblique angle from the interior of the housing 2 is an inlet connection 3, which is secured to the receptacle 1 in any desired way. Projecting from the opposite side of the casing-2 is a discharged nozzle 4, which is also by preference disposed at an oblique angle to the interior of said housing 1 so as to discharge downwardly. 5 is a removable ca for one end of the housing 3. 6 is a remova le cap for the other end of the housing 3. These caps are secured to the housing in any suitable way, as by screw threads, so as to make a tight joint. 7 is a valve tapered to fit in the housing. The stem of the valve projects outwardly through cap 6 and carries a handle 8. Between the cap 6 and the upper end of the valve 7 is a spring 9, which tends to keep the valve snugly seated in the tapered bore in the housing 2. The bottom of the valve is provided with two segmental stop 1931. Serial No. 565,716.

members, indicated respectively at 10 and 11. 12 is a stop pin, whichpasses diametrically through the bottom of the housing and stands in the spaces between the stop members 10 and 11 so as to permit the valve to be given approximately a quarter turn in either di rection. I

At opposite sides of the valve body 7 are two recessed portions, indicated respectively space 12. When it is desired to discharge a the fluid from space 12, the valve is turned by they handle in a clockwise direction as viewed in Fig. 1, thus turningthe space 12 into a position to register with thedischarge nozzle 1, through which said measured contents'may then flow out. This movement of the valve puts the measuring space 13 in com munication with the int-eriorof the receptacle 1 through the inlet 3,,so that partof the contents'may then flow into and fill this space. When it is desired to discharge the liquid in space 13, the valve is turned back again to the position shown in Fig. 4, causing space 13 to register with the outlet nozzle 4.

Tam aware that measuring valves of this type are" not broadly new, but heretofore great difiiculty has been experienced in properly cleaning the interior wall of the inlet 3 and the interior wall of the outlet nozzle 4. By the present construction this cleansing of these walls may be quickly and perfectly done, since by removing the cap 6 and withdrawing the valve, the openingat the top of the housing'Q gives complete and perfect ac cess to the boreof the inlet 3 and the bore of the discharge nozzle 4. It will be noted that in my device the projection of the bore of the inlet 3 and the projection of the bore of the discharge nozzle 4 both pass through the opening in the end of the housing 2, through which the valve '7 is inserted and restitute a medium for breeding dangerous i bacteria and thus contaminate fresh milk or.

cream passing therethrough. It is there fore exceedingly important not only'to make a the act of cleaning easy, but also to permit of ready inspection. To that end Ihave-so constructed the housing and associated parts that by the mere act ofremoving the cap 6 and the valve 7 the user may accomplish this cleaning'operation easily and quicklywand.

may actually look through said bores to see whether his work has been thoroughly done. 14 represents a vent that may be provided in the side wall of the housing 2. 15 represents a vent passage in one side of the valve 7 leading to the space 13. When the space 13 registers with the nozzle 4 these vents 1415 register to permit air to enter the space 13 and thus permit the ready outfiowof the liquid contents of the chamber 13. Similar vents may be provided on the otherside of the measuring device to vent the space 12' when the latter registers with the discharge nozzle.

.What I claim is:

1. In a measuring valve, a valve housing, a valve mounted therein and having measuring chambers in opposite sides thereof, said valve being rotatableto two different operative ,positions,-an opening in the outer end of the housing for permittin thevalve to be inserted and removed, a cap or said opening, an inlet projecting angularly from the side wall of the valve housing, the projection of the bore of said inlet passing through the opening in said housing through which the valve is inserted and removed, a discharge nozzle on the opposite side of said housing,

the passage through the nozzle and the passage through the-inlet registering alternately with the measuring chambers in said valve as said valve is rotated from one to another of its operative positions. 7 r

2. In a measuring valve, a valve housing, a valve mounted therein and having measuring chambers in opposite sides thereof, said valve being rotatable to two different operative positions, an opening in the outer end of the housing for permitting the valve to be inserted and removed, a cap for said opening,

It is well known bore through said nozzle passing through said opening in said housing.

3. In a measuring valve, a valve housing, a valve'mountfli therein and having measuring chambers in opposite sides thereof, said valve being rotatable to two different operative positions, an opening in the outer end of the housing for permitting thevalve to be inserted and removed, a cap for said opening, an inlet projectingangularly from the side wall of the valve housing, the projection of the bore of said inlet passing through the opening in said housing through which the valve is inserted'and removed, a discharge a nozzle on the. opposite side of said housing, the passage through'the nozzle and the passage through the'inlet registering alternately with the measuring chambers in said Valve assaid valve is rotated from one to another of its operative positions, and a stop mechanism at the bottom of said valve to permit said valve to be rotated only approximately one quarter of a turn. 1

4. In an apparatus for dispensing liquid foods,a container, a dispensing valve mechanism therefor, comprising a valve housing having an opening at one end, an inlet leading from said container into said valve housing and directed toward the open end of the latter, to :afiordfree access intothe same for inspection and. cleaning from the outside of the housing, a valve removably mounted in said housing to control said inlet passage, and

, an outlet passage from said housing. 1

v5. In an apparatus for dispensing liquid foods, a container, a dispensing valve mechanism therefor,-comprising a valve housing having an opening at one end, an inlet leading from said container into said valve houss ingand directed toward the open end of the latter, to afford free access into the same for inspection and cleaning from the outside of the housing, a valve removably mounted in said housing to'control said inlet passage, and an outletpassage from said housing, said outlet passage being also directed-toward said opening to facilitate inspection and cleaning of the same when said valve is removed.
